This is used to support multi-thread JavaScript by node addon as below.
A node addon can be created to initialize v8 Isolates in separate threads, which is used to run JavaScript in multi-thread. It requires the MultiIsolatePlatform (used in the node main thread) to register those isolates respectively.

As an example you may concern, when we try to re-implement napajs Worker::WorkerThreadFunc by node public APIs, it seems node::GetNodeMultiIsolatePlatform is a missing piece from node API.

#20239 is also an issue about this topic. @fs-eire

Maybe specific that the macro needs to have been defined when Node.js was built, not when the addon is being built?

Also, what's "node main"? This comment could be expanded a little.

Redundant name, it's already in the node:: namespace. Just GetMultiIsolatePlatform() or GetMainThreadMultiIsolatePlatform()?

change it to GetMainThreadMultiIsolatePlatform as a more accurate name.

LGTM, I think. The commit log should conform to the style guide, though.

Suggestion: it returns instead of it would return.

BTW, I just made the commit log confirm to the style guideline to my best knowledge. Please help modify it if anything required when you help squash and merge it.
